Paul, As of 3.18-rc1 I can no longer hibernate my Dell XPS-13. Bisect points the finger at 35ce7f29a. A revert of that commit confirms, I can once again hibernate my machine without it.
When the hibernation fails I see this in dmesg: [ 37.953313] PM: Syncing filesystems ... done. [ 37.963694] Freezing user space processes ... (elapsed 0.001 seconds) done.

I am not sure what else I can provide that might be useful, but I did see the thread on net-dev about this same commit. Please CC me on any fixes and I will be happy to test.
